Cownose Ray
Rhinoptera bonasus
A schooling ray that migrates in huge schools along the Atlantic and Gulf coasts, entering Chesapeake Bay in summer, and is named for its lobed snout, which looks like a cow's nose. Its reputation for destroying Chesapeake oyster beds is debated — studies suggest its impact was overstated and that shark declines were also involved. Most anglers release it, staying clear of its tail spine.

Identifying features
- Blunt, double-lobed snout like a cow's nose, set in front of the eyes
- Broad diamond disc, brown to olive above and white below, with a pointed snout profile from above
- Short whip tail with one or two small serrated spines at its base
- Strong flat tooth plates for crushing clams, oysters and other shellfish
- Usually 3-4 ft (0.9-1.2 m) across, smaller and shorter-tailed than a southern stingray
Habits
- Migrates in huge schools, sometimes hundreds strong, swimming near the surface with wingtips breaking the water
- Feeds in groups over shellfish beds, flapping and digging to expose clams and oysters
- Its Chesapeake oyster-eating reputation is debated — present carefully, as studies suggest the impact was overstated
- Enters Chesapeake Bay in late spring, leaves for warmer water in fall, and gives live birth to one pup
- The tail spine is small but venomous; handle at the disc edges and release in the water
Distribution
Where to find them
- Chesapeake Bay shallows and shellfish beds in summer
- Carolina surf and nearshore migration routes in spring and fall
- Florida Atlantic and Gulf bays when schools pass through
Where they live
How to catch them
Bottom rigs with clam or crab in bays Boat
Rig: Medium-heavy rod, bottom rig with a 4/0-6/0 circle hook and clam or crab, fished over shellfish beds when schools move into bays
Bait/lure: Clam, crab
Key tip: Most are released — keep the ray in the water, watch the small spine at the tail base, and support the disc.
Sight-casting to migrating surface schools Boat
Rig: Medium-heavy spinning rod, a small lead-head jig or bait cast ahead of a moving surface school from a boat
Bait/lure: Small jig, cut bait
Key tip: Cast ahead of the school, not into its centre, and expect a long, powerful first run.
